Reporting Timing Advance Information in Non-Terrestrial Networks

1. A method comprising: receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure, wherein the one or more configuration parameters comprise a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value; triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied; triggering a scheduling request (SR) and starting an SR prohibit timer, based on the triggering the TA reporting procedure; transmitting a TA reporting information via one or more uplink shared channel (UL-SCH) resources; canceling the triggered TA reporting procedure; and cancelling the triggered SR and stopping the SR prohibit timer, in response to the canceling of the triggered TA reporting procedure.

2. The method of claim 1, wherein: the TA reporting information is transmitted via a medium access control (MAC) control element (CE) or a radio resource control (RRC) message; and the TA reporting information is based on a location information of the wireless device or a current TA value of the wireless device.

3. The method of claim 1, further comprising: calculating a user-equipment (UE)-specific timing offset based on receiving a timing offset; and discarding the UE-specific timing offset based on the canceling the triggered TA reporting procedure.

4. The method of claim 3, wherein the receiving the UE-specific timing offset is in response to the transmitting the TA reporting information.

5. The method of claim 3, further comprising restarting the SR prohibit timer based on receiving the UE-specific timing offset.

6. The method of claim 1, wherein the transmitting the TA reporting information comprises transmitting the TA reporting information via a random access (RA) procedure based on determining that transmitting the TA reporting information via the RA procedure is configured by the one or more configuration parameters.

7. The method of claim 1, wherein the triggering the SR is to request the one or more UL-SCH resources.

8. The method of claim 1, further comprising receiving a radio resource control (RRC) reconfiguration message indicating one or more configuration parameters of a non-terrestrial network (NTN), wherein the cancelling the triggered TA reporting procedure is in response to the receiving the RRC reconfiguration message.

9. The method of claim 1, further comprising in response to the transmitting the TA reporting information, stopping an ongoing random access procedure for the triggered SR, wherein: the SR has no valid physical uplink control channel (PUCCH) resource; and the UL-SCH resources are indicated by at least one of a Type 1 configured grant or a Type 2 configured grant.

10. The method of claim 9, wherein the UL-SCH resources are not associated with the ongoing random access procedure.

11. The method of claim 9, wherein the one or more configuration parameters indicate the UL-SCH resources, wherein the UL-SCH resources are based on the Type 1 configured grant or the Type 2 configured grant.

12. A method comprising: sending, by a base station to a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure, wherein the one or more configuration parameters comprise a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value, wherein the configurations are configured to cause the wireless device to trigger the TA reporting procedure based on a condition for the first timing advance threshold being satisfied; to, based on the TA reporting procedure being triggered, to trigger a scheduling request (SR) and starting an SR prohibit timer; to transmit a TA reporting information via one or more uplink shared channel (UL-SCH) resources; to cancel the triggered TA reporting; and, in response to the canceling the triggered TA reporting procedure, to cancel the triggered SR and to stop the SR prohibit timer.

13. The method of claim 12, further comprising sending a radio resource control (RRC) reconfiguration message indicating one or more configuration parameters of a non-terrestrial network (NTN), wherein the triggered TA reporting procedure is cancelled in response to the RRC reconfiguration message.

14. A wireless device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to perform: receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure, wherein the one or more configuration parameters comprise a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value; triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied; triggering a scheduling request (SR) and starting an SR prohibit timer, based on the triggering the TA reporting procedure; transmitting a TA reporting information via one or more uplink shared channel (UL-SCH) resources; canceling the triggered TA reporting procedure; and cancelling the triggered SR and stopping the SR prohibit timer, in response to the canceling of the triggered TA reporting procedure.

15. The wireless device of claim 14, wherein: the TA reporting information is transmitted via a medium access control (MAC) control element (CE) or a radio resource control (RRC) message; and the TA reporting information is based on a location information of the wireless device or a current TA value of the wireless device.

16. The wireless device of claim 14, wherein the instructions, when executed by the one or more processors, further cause the wireless device to perform: calculating a user-equipment (UE)-specific timing offset based on receiving a timing offset; and discarding the UE-specific timing offset based on the canceling the triggered TA reporting procedure.

17. The wireless device of claim 16, wherein the receiving the UE-specific timing offset is in response to the transmitting the TA reporting information.

18. The wireless device of claim 16, wherein the instructions, when executed by the one or more processors, further cause the wireless device to perform restarting the SR prohibit timer based on receiving the UE-specific timing offset.

19. The wireless device of claim 14, wherein the transmitting the TA reporting information comprises transmitting the TA reporting information via a random access (RA) procedure based on determining that transmitting the TA reporting information via the RA procedure is configured by the one or more configuration parameters.

20. The wireless device of claim 14, wherein the triggering the SR is to request the one or more UL-SCH resources.
